Maleperduys

Maleperduys (or "Maupertuis") is Reynard the Fox's principal hideaway in the medieval tales of this figure of legend.

Labyrinthine Maleperduys is full of holes, crooked and long, with multiple exits, which Reynard can open and shut to elude his enemies. Full of secret chambers and passageways, in William Caxton's "The Historie of Reynart the Foxe" (1485) the castle of Maleperduys is described as the "best and the fastest burgh that [Reynart] had. There lay he in when he had need, and was in any dread or fear." (Chapter VII, "How Bruin the Bear was sped of Reynart the Fox").
